The invention relates to a method for extracting camellia oleifera seed oil, sasanqua saponin and camellia oleifera seed meal feed from camellia oleifera seed kernels. The method includes the steps that camellia oleifera seed oil is extracted by means of an aqueous phase, then sasanqua saponin in residues is extracted by means of ethyl alcohol solutions with gradually increased concentrations in a reverse extraction mode, and remaining residues are camellia oleifera seed meal feed. By means of the method, the oil extraction rate can reach 93-95%, and the purity of the obtained sasanqua saponin is higher than 60%. The unique fragrance of the camellia oleifera seed oil can be kept, and it is also guaranteed that fat-soluble components in the camellia oleifera seed kernels are fully maintained in the camellia oleifera seed oil. Ethyl alcohol used in the method is in a food grade, safe, free of toxin and capable of being recycled. Extraction water in use can be recycled through regeneration, no sewage or waste residues are discharged in the whole extraction process, and production application prospects are very wide.
